What is Induced Charge Specifically

The phenomenon that the charge generated when a conductor approaches a charged object is distributed on the surface of a conductor. For example, if the conductor D is close to the charged body X, the electric field established by the negative charge on X in D will push the free electrons to the far side of D, and leave the same amount of positive charge on the near bar of D until the electric field strength in D is zero. Conductor D has a positive charge due to the loss of electrons, and this positive charge is called induced charge, which can also be called induced charge.

The induced charge you're talking about should be the kind caused by friction, not what the upstairs says.

We know that an uncharged object is because it has an equal number of positive and negative charges, but some objects will move electrons due to friction or other external reasons, and this movement will cause one side to lose electrons and one side to gain electrons, because electrons are negatively charged, so those who lose electrons are positively charged, and those who gain electrons are negative......ly charged, and those who gain electrons are negatively charged

Charge generated by electrostatic induction.

The current generated by the closed coil cutting the magnetic inductance line in the magnetic field is the induced current.

The total electric field in the metal ball is empty 0, therefore, the induced charge bucket on the metal ball is coded in the metal ball The electric field strength of the three points A, B, and C is equal to the electric field strength generated by the charge on Mn at these three points (the direction is opposite). The closer the point to the mn, the stronger the field strength, so, EA

It should be option d, n is easy to understand, put a positive charge inside, the inner surface must induce a negative charge, the outer surface must have a positive charge, and the outer surface must have a positive charge, and there must be a field strength outside, so there must be an induced charge on r, m is similar, before putting in the positive charge, there is a negative charge inside, a positive charge on the inner surface, and a negative charge on the outer surface, but after putting in a positive charge, the sum of the internal charges is 0, so there is no longer an induced charge on the inner and outer surfaces, there is no field strength on the outside, and there is no induced electric history on p.

Induced charge is a phenomenon in which an electric charge is moved closer to an uncharged conductor, which can be electrified. The use of electrostatic induction to electrify an object is called inductive electrification.

The charge q that should be produced by a charge inductance q is less than or equal to this charge, i.e., q'≤q。

For example, if there is a charge q in a closed spherical shell, then the charge q = q induced on the spherical shell

When the charge q is outside the sphere, the induced charge q < q, the specific amount depends on the distance between the two, the closer the charge q is induced, the less it is.

When electrostatic induction, the charge will repel the same species as far as possible and attract the dissimilar species as close as possible, so the inner surface of the cavity difference cavity is positively charged, and the outer surface is negatively charged to achieve electrostatic equilibrium (the positive and negative charges induced are balanced by the Coulomb force); After the cavity is grounded, the electric potential changes, the negative charge has a farther place to move, the force balance is disrupted, the charge is redistributed, and the negative charge is repelled by the internal negative charge and flows into the earth.

You have to distinguish the causal relationship clearly, the internal negative charge is the cause, the positive and negative bending Zheng Hui charge induced is the effect, there is no effect without the cause, and the result obeys the cause. Although the negative charge on the outer surface is also attracted by the positive charge on the inner surface, the reason for the separation of the positive and negative charges is the Coulomb force of the negative charge on them in the cavity, which repels the same charge as far as possible.

How much is one charge? There is no such measure. The amount of induced charge is generally less than or equal to the amount of charge of the field source.
